I'm pretty sure that's all in order, especially since it works as soon as
I move everything to Tioga:
edwin at zaphod:~$ cat /usr/bin/tioga
#!/usr/bin/env ruby
#
# This file was generated by RubyGems.
#
# The application 'tioga' is installed as part of a gem, and
# this file is here to facilitate running it.
#

require 'rubygems'
version = "> 0"
if ARGV.size > 0 && ARGV[0][0]==95 && ARGV[0][-1]==95
    if Gem::Version.correct?(ARGV[0][1..-2])
      version = ARGV[0][1..-2]
      ARGV.shift
    end
end
require_gem 'tioga', version
load 'tioga'

edwin at zaphod:~/tmp/samples$ tioga sample.rb -l
/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in `require__':
no such file to load -- Tioga/tioga_ui.rb (LoadError)
          from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in
`require'
          from /usr/lib/ruby/gems/1.8/gems/tioga-1.4/split/scripts/tioga:2
          from /usr/bin/tioga:18:in `load'
          from /usr/bin/tioga:18

I also tried the following, but got the same error message:
require 'rubygems'
version = "> 0"
if ARGV.size > 0 && ARGV[0][0]==95 && ARGV[0][-1]==95
    if Gem::Version.correct?(ARGV[0][1..-2])
      version = ARGV[0][1..-2]
      ARGV.shift
    end
end
#require_gem 'tioga', version
#load 'tioga'
require 'Tioga/FigureMaker'

BTW I now tried it on another machine (although still gentoo and gcc
4.1.1) and still the same problem

The end :)
